The Save the Children Fund in Sri Lanka says that a hand grenade was
thrown into its office compound in Colombo early on Tuesday.

A
spokeswoman for the aid agency said that because the grenade exploded near
a tree it caused some damage, but no injuries.

The attack has been linked by commentators to the resentment felt
by some in Sri Lanka to Oslo's ongoing mediation efforts.

Norway has its
own office within the SCF's compound in Colombo and along with Britain
plays a prominent role in the running of the organisation.

A statement
released by SCF says that Save the Children-Norway has no involvement with
the initiative of the Norwegian Government to mediate in the Sri Lankan
civil war.

It says that the SCF is a humanitarian organisation which strictly
follows a policy of neutrality.

Norwegian effort

A spokeswoman for the Norwegian embassy in
Colombo confirmed that Mr Solheim arrived in Sri Lanka on Monday and is due
to meet with politicians and community leaders representing all
sides in the Sri Lankan war.

Last month, an explosive device was thrown next
to the embassy's precincts and caused minor damage.

The Norwegian
ambassador, John Westborg, said at the time that he believed the attack
was carried out because of his country's efforts to end the fighting.

The
Sri Lankan police, however, issued a statement saying that they did not
believe that the Norwegian embassy was the target of the attack.

'Interference'

In April,
Buddhist monks staged a demonstration outside the embassy in which they
burnt a Norwegian flag in protest at what they said was Oslo's interference
in the internal affairs of a sovereign country.

They accused the Norwegian
Government of allowing the Tamil Tigers to raise funds in Norway.

Meanwhile,
police and bomb squad officers are examining the scene of the latest
explosion.
